4227-514AD MINNESOTA RUBBER QUAD RING

Part number VQ4227 is an AS568-227 black Viton® (FKM) 75 Shore A quad profile Quad-Ring built to an inside diameter of 2.109 in (53.57 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.387 in (60.63 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

This material stands up to chlorinated solvents, aromatic hydrocarbons, and many acids. That behavior comes from the compound itself: Viton® (FKM) is specified for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

Maintenance and OEM teams specify it across semiconductor equipment, automotive fuel systems, and oil and gas.

This item is sold individually under part number VQ4227. Review your operating media and conditions against this specification before installation.
